MACHINE FOR MAKING CLAY PIPES.

Specification of Letters Patent No. 24,174, dated May 24, 1859'.

To all whom it may concern:

Be it known that we, HENRY AizEGooD, of Mansfield township, in Burlington county and State of New Jersey, and STEPHEN Us'ricK, of the city of Philadelphia and State of Pennsylvania, have invented a new and useful Machine for Making Clay Pipes for Hydraulic and other Purposes, and that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, in which- Figure l, is a top view of the machine. Fig. 2, is a side elevation of the same. Fig. 3, is a longitudinal section through the line X, K, of Fig. l. Fig. 4 is a front view of the grate E. Fig. 5, is a top view of do. Fig. 6, is a front view of the die F. Fig. 7, is a top view of the same. Fig. 8,'is a perspective view of the core pin I-I. Fig. 9, is a front view of the cutter I. y

Like letters in all the gures represent the same parts of the machine.

Our invention consists in certain improvements in machines for making bell end pipes.

To enable others skilled in the art to make and use our invention we will proceed to describe its construction and operation.

, A, is the standing frame to which the lseveral parts of the machine are attached,

A', is a continuation of frame A, which forasmuch as it does not have to sustain much weight is made much lighter than the frame A; and is made to detach from the said frame at pleasure for convenience in moving.

B, is the trough through which the clay is forced to form the pipes.

C, is the hopper which contains the prepared clay.

D, is a slide, in the bottom of the hopper C, which cuts off the communication between it and the trough B, while the pressing is performed it fits in appropriate grooves in the hopper, and in grooved pieces a, a, in the rear of the same.

E is a grate near the front end of the trough B, through which the clay is forced and thence in its passage through the die F, of plate F.

Gr is a mold for forming the outside of the lbell end of the pipe-the said mold being made in two-pieces to open and close for the purposes that will be .explained below. They have arms b, b, and ZJ', Z9', which slide in grooved pieces c, c, iii front of the main frame A.

H, is a core pin that gives shape and size to the inside of the bell end of the pipe. The inside end has a steady pin that fits in a hole in the center of the die plate F, and it has a ring g which rests back of a rabbet of the mold Gr, to hold it in its longitudinal position vwhile the bell end of the pipe is being formed.

I, is the cutter which cuts the pipe from the die at the termination of each forward stroke of the piston J.

K, is the driving shaft.

L, is a cam wheel on the driving shaft K, its rim L, running between the frictionY wheels g and L, in the rear end of the piston frame J.

M, is a cam wheel on the driving shaft K, whose rim M', running between friction wheels Z and m, on the rear end of the shaft N, which slides in grooved piece c, operates the same, the front end of said shaft being connected by means of pnswith the arms n, n', of rock shafts O, O,and the arms 0,0 and 0, o being connected by means of the pins p, p, with the slides b, and b, J, of the mold Gr, the requisite motions and positions are given to both halves of said mold as will be hereafter described.

Q, is a cam strip on theY reverse sidev of the cam wheel L, and is represented by red lines in Fig. 2. Its office is to give a reciprocating motion to the slide D, to which the front end yof the rod R is attached. The rear end of the said rod slides in the grooved piece y. The said cam strip Q, runs beward, and thus spreadin U, by means of the friction wheel u, and the arm lw, with the cutter I by means of the pin X.

The endless apron V, encircles the series of rollers a', a', a', &c. and is made to run freely therewith'to carry forward the pipe otherwise it causes the driving shaft K, to4

revolve with the cam wheels attached there-l to in the direction of the arrow. And as the outer periphery e, of the rim L', of the cam wheel L, from the point 1, to the point 2, passes the friction wheel g, of the piston frame J, said segmental portion being an eccentric curve, the point 2 being farther from the center of the driving shaft K, than the point l, the pisto-n is movedforward in the trough B, and forces the'clay through the die F into the mold G, and fills `the same and thus forms the bell end of the pipe. The piston is' then allowed toV remain Stationary while the said outer periphery e, of the rim L', from the point 2 to the point 3 passes the friction wheel g, said portion of the rim being a concentric curve scribed from the center of theA driving shaft K. During which time the outer periphery j of the rim M', 'of the earn wheel M, from the point l to the point has passed the friction wheel Z, on the shaft N, and said portion ofthe rim being an eccentric curve the point 2, being farther from the center of the driving shaft K, than the point l, the said shaft is forced forward moving the arms n, n', of the rock shafts 0,' O', forward and consequently the arms 0, o, upward and the armsvo, o', downthe upper and lower parts of the 'mold apart to allow the belt end of the pipe just formed, and the core pin H to pass freely out of the same. The halves of the mold G, are Aheld in said position while the 'outer periphery y' from the point 2, to thepoint 3, which is a concentric curve, scribed from the 'center of the driving shaft K, passes the said -frie-Y tion wheel Z. The inner periphery '76, vof the rim M', of the cam wheel M, from the point l, to t-he point 3, has no office to perform and is made parallel with the Iouter periphery Vbetween said points to freely pass the friction wheel m, on the shaft N. The outer periphery e, of therim L', of the cam wheel L, fro-m the point 3, tothe point 4 is an eccentric curve, the pointe, being farther from the center of the driving shaft K, than the point 3, and as it passes the friction wheel g, it forces the piston J, forward and presses the clay in the trough B, through the die F', and forms the small, or straight part of the pipe, the

bell end in the meantime advancing f0rward and the bottom side of foot of the kcore pin I-I, resting on the apron V, and sliding over the rollers a', a', a', a',&c., to prevent the pipe touching the same. The piperbeingthus formed 1t is cut ott' from the vdie Ali" by means of the cutter I, asfollows. The groove U, in the side of the driving wheel S, from the point 1, tothe point 2, being an yeccentric curve operating on the friction wheel u, on the arm o, of `rock shaft T, forces the said arm upward and arm 'w downward which carrying the cutter I, with it causes the latter to cut the of the pipe having terminated ,when 1 the point 4 'of the 'outer periphery e, of `-the -rim L', of the cafrn wheel L hasreached'the friction wheel y', and the lpoint l ofthe inner periphery f, 'has reached the Vfriction wheel' h, of the piston framejJ, `the "said inner peripheryV f, takes a vrapid turnfin ward, toward the center of the driving shaft-K, from the said peint 'to -theupoint ward with the ifrontend of the piston to the rear side of :the `h'cipper jC. During th'e backward motionthus describe-d of the @pisma J., 'the slide nia fue beam 'of the `hopper C, is made to recede with its 'front end even with the rear side of the 1hopper to aliowgtiie 'clay in the 'same to descend into, and lill the trfuh AB, 4said backward `inotion 'of the sl'ide being by the outer periphery YJ' of the 'can strip Q, from the point i, to thepoint 2, pressing against 'the friction wheelZ, on the rear'end of 'the rod R, saidportion y0i the periphery being `an eccentric curve, the point 2, being `farther from the center of the driving shaft K, than the point 1". The saidfouter periphery then assumesV a concentric curve from the point 2,110 the point '3, tokeep the slide D, stationary a short time to allow the ela'y time to 'descend frein-the hopper C, into the troughv B. The inner periphery o", then takes a rapid turnV inward toward fthe lcenter o'f the driving shaft K, the point '4l being nearer the "center of 'the ASaid 'shaft than the point 8, and bearing against the friction whe'el Z', forces the slidev D, forward Awith its Yfi"- `int end touching the `'frfi'i'it side of V"the hopper C, "and to prevent the clay passing out ofthe trough B, "eX- cept throughthe die F', the continuation of the 'sa-1d innerperiphery -of the vstrip 1Q',

from the point 4, to the point 5, is a concentric curve scribed from the center of the driving shaft K, and by impinging on the friction Wheel Z, prevents the slide D, rebounding. During the forward motion thus described of theslide D, the piston J, has been held stationary by the inner and outer peripheries e and f of the rim L, of the cam Wheel L assuming a concentric curve from the point 5, to the point 1, the place of beginning.

All the motions which are necessary to the formation of a single pipe have been described in one revolution of the driving shaft K. By multiplying the revolutions of the shaft, the number of the pipes Will be multiplied accordingly. As the core pin H, has to be inserted in its place Within the mold Gr, before the closing of the 2 halves of the latter, We design having several of the same size, in order to secure certainty of one or more being in reach of the person attending the machine at all times.

We purpose using the above described `machine for making straight pipes and draining tile, in Which case We detach the mold G, and core pin H, and their connections.

Having thus fully described our improvement We do not purpose to claim the mold, core pin, or knife or cutter, as these devices are employed in the machine patented by C. P. Wardwell April 21, 1857 butare there operated in combination with levers by a different arrangementof parts and by gearing, but

What We do claim as our invention and desire to secure by Letters Patent is-` l. The annular ring g, upon the core pin H, (which is also provided With a foot) in combination With a flange upon the inside of the outer front end of the mold Gr, to retain the core pin in place While forming the bell end of the pipe operated in the manner and for the purposes specified.

2. The cam Wheel L, in combination with the piston J, trough B, and its connections, mold G, and core pin H, for making the bell end and straight part of the pipe at one operation.

3. The combination of the rock shafts O and O, with the 2 halves of the mold Gr, the former being operated by the cam Wheel M, and shaft N, for the purposes above described.

4. The slide D, rod R, and cam strip Q, arranged as described for the purpose above set forth.

5. The arrangement and combination of the cam U, rock shaft T, and levers W, and lu, for operating the knife I in the manner and for the purpose specified.

In testimony that the above is our invention We have hereunto set our hands and aiiiXed our seals this nineteenth day of February, 1859.
